Title: Smart Bus Information Terminal employing IoT
Inventor: JEONG HYUN CHAN
IPC: G01J1/02
Filed: 2021-06-25
Granted: 2022-01-25
Abstract: An embodiment relates to an IoT-based smart stop guide terminal. Specifically, when a stop guide terminal provides a stop guide service, such a smart stop guide terminal uses an environment control board with an Internet network communication (wired communication) function separate from a main control system to determine the conditions around a stop and a stop guide terminal. The IoT-based smart stop guide terminal monitors the system by collecting various status information such as the main control system, display, and communication modem, and performs individual control for each different status. Also, such an environment control board enables individual communication and control without a command from the main control system. Therefore, the embodiment reinforces self-diagnosis and the watchdog function for major parts through a smart stop guide device. Even in the event of a failure, the embodiment recovers quickly and minimizes downtime, thereby improving the convenience of bus stop guidance and improving service quality.
